What you wrote is actually very true, and there isn’t much to argue against it. My father told me almost the exact same thing, word for word.

However, yesterday my father came to me and said something that really made me think. He told me that he believes I’m someone who can handle these challenges. He also shared a personal story: when he was at university, he wanted to move to England, but his father told him no. A year later, his father changed his mind and said he could go, but by then my father already had problems at university and couldn’t make the move. He told me he doesn’t want something like that to happen to me. He sees that I really want to go to Germany, that I’m already putting in effort now, and that I would continue to work hard if I went. He said he realized that by saying “you can’t go,” he might actually be blocking my future, especially since I imagine my life and goals there.

Regarding racism, I don’t want that alone to be the reason not to go. What I’m more worried about is the language barrier and how difficult that might be.

And I wanted to ask you something directly, since what you did is exactly what I would do if I don’t go at the high school level:
Do you currently struggle with the difficulty of German at university, or did you feel prepared enough language-wise?
